Application filed November 11, 191.2. Serial No. 730,5;2.

To all whom it may concern:

Be it known that we, GEORGE F. HUTCHINS and EPPA H. RYoN, citizens ofthe United States, residing, respectively, at Worcester,

in the county of Worcester, and State of,

Massachusetts, and Waltham, in the'; county of Middlesex and State ofMassachusetts, have jointly invented certain new and useful Improvementsin Weft-.Replenishing Looms,

of which the following is a specification.

Our invention relates to weft replenishing looms in which there areshifting shuttle boxes for a plurality of shuttles at one end of theloom, and a single shuttle box, and a ries the bobbin above thestationary shuttle box on the lay, preparatory to being transferredintothe active shuttle.

The stationary magazine, above referred to, is in this instance of thetype shown and described in U. S. Letters Patent, No. 1,022,109, and inour present improvements we combine this stationary magazine withmechanisms on the loom for raising the single shuttle box, which carriesthe active shuttle, to receive the new bobbin direct from the conveyerof the stationary magazine, Without using the transferrer arm ordinarilyemployed.

The mechanisms referred to for raising the shuttle box on the plain endof the lay, are in this instance of the type shown and described in U S.Letters Patent, No.

In the operation of the loom, when a change of filling is indicated, onthe practical or substantial exhaustion of filling in the activeshuttle, the bobbin, which has the same color or character of fillingthereon as the bobbin in the active shuttle, will be dropped from acompartment of the stationary magazine into the conveyer, and on thefurther movement of the releasing mechanism, the conveyor, with thereleased or dropped bobbin, will be moved to the center of the magazineand into a position above the shuttle box, when the lay has been movedto its front position. At the same time a lever on the stationarymagazine is raised,

' and through intermediate connections, operates a sliding or startingtooth on a mutilated pinion, to move said sliding tooth into mesh with amutilated gear on the bottom shaft of the loom, which causes saidmutilated pinion to be revolved, and through an eccentric thereon,operate an angle lever,

which is adapted to raise the single shut-' the box 'on the lay, withthe shuttle and the exhausted bobbin in the shuttle. The lower portionof the conveyer enters the active shuttle, and delivers a new bobbin tothe same.

The raising and lowering of the single shuttle box on the lay is sotimed, that its full operation will be accomplished in less than halfthe strokeof'the lay.

Our invention consists 'in' certain novel features of construction ofour improvements, above referred to, as will be hereinafter fullydescribed.

We have shown in the drawing a detached portion of a stationary magazineof the type above referred to, with a shuttle box raising mechanism ofthe type above referred to, combined therewith, sufiicient to enablethose skilled in the art to understand the construction and operationthereof.

Referring to the drawings Figure 1 is an end view of a loom frame,carrying a stationary magazine of the type Patentc Apr. 3, T917.

above referred to, with the shuttle box opcrating mechanism supportedthereon, looking in the direction of arrow at, Fig. 2-.

Fig. 4 shows, on an enlarged scale, a sectional view of the butt end ofthe shuttle shown in Fig. 2, and the lower end of the conveyer arm, andthe lower central portion of the magazine.

Fig. 5 is a section, on line 5, 5, Fig. 4,

looking in the direction of arrow d, same' shaft 7, 8 is the bottomshaft of the loom,

see Fig. 1. 9 is a' stand secured to the breast beam 2 and loom side 1,which has rigidly connected thereto the inner end 10 of the stationarymagazine, which has in this instance six vertically extendingCompartments or guide-ways 10, see Fig. 2, for,the heads or butts 11 ofthe bobbins or filling carriers 11. i v

Carried on the transverse rods 12 is the outer end 13 of the stationarymagazine, with six vertically extending compartments for thetips of thebobbins 11. Each compartment or guide-way is provided at its lower endwith mechanisms for supporting the sets of bobbins therein, and also forre-.

leasing the lowest bobbin in each set, preparatory to being conveyed tothe discharging center of the magazine, to be transferred into theactive shuttle.

The holding and releasing means consists in this instance of slidingbars or blades 14, see Fig. 3, which are guided at each end thereof, andwhich blades, through the sliding movement communicated thereto, movefrom underneath the bobbins to release and drop the bobbins in the usualway.

On the inner side of the inner end 10 of the magazine, are sixvertically moving bars 15, see Fig. 2, one for each compartment. Thesebars are loosely supported in guides 101, and have an up and downmovement therein. The bars 15 are provided at their upper ends withweighted hooks 16, which are adapted, on their downward movement, tocommunicate and rock the lever 17, which has its hub 17 secured on therock shaft 7 .18. Bearings 10'', see Fig. 3, on the magazine, haveloosely mounted therein a longitudinally moving rod 19. A sliding motionis communicated to the rod 19, through angle lever 20, see Fig. 1,which, through a connector 21, and chain or cord22 from the shiftingshuttle boxes on the opposite end of the loom, not shown, receives areciprocating movement, to cause the rod 19 to move longitudinally intosix difi'erent positions, according 'to the position of the shiftingshuttle boxes.

nections thereon, not shown.

The rocking movement of the lever 24 will, through its engagement withthe extension 15 on the "ertically moving bar '15, move up or down aselected bar 15, and

through the connection of each bar to the sliding blades 14, release andallow a bobbin 11 to drop from its compartment.

The operating lever 20, see Fig. 1, has an arm 25 rigidly connectedthereto, which is adapted to loosely receive a sliding block 26, seeFig. 3, which in its normal position rests upon a pin 27 at the lowerend of the arm 25. The block 26 carries a stud 28, which has pivotallyconnected thereto one end of the rod or connector 29; the other end ofthe connector 29 has pivotally connected thereto a stud 30, which isfast on the end of a downwardly extending arm 31, which has its hub 31loosely mounted, in this instance on a transverse shaft 32, which isjournaled in suitable bearings on the inner end 10 and outer end 13 ofthe magazine.

Also loosely mounted on the shaft 32 is the hub 33 of an arm 33, whichextends toward the rear of the magazine, and has its end, when in itslowered position, coincide with the axis or fulcrum of the arm 25. Astud 34 on the end of the arm 33, has pivotally connected thereto theupper end of theconnector 35; the lower end of said connector 35 isconnected to the stud 28 on the sliding block 26, see Fig. 3. A bolt orscrew 36, on the arm 33, has loosely pivoted thereon the lower end of anupwardly extending latch 37. The upper end of the latch 37 has a pin 38extending outwardly therefrom, and is adapted to be engaged by the arm17 on the lever 17 see Fig. 2, to move upwardly the arm 33, as shown.

A stud 39 on the arm 33 has pivotally connected thereto the upper end ofa vertically extending connector 40; the lower end of said connector 40is pivotally connected to a stud 41 on a lever 42, which has its hub 42loosely mounted on astud 43 on a stand 44. Extending rearwardly from;the hub 42' is an arm 45 which has the engaging end 45, adapted to beengaged by the lay on its backward. motion, to re-set and movedownwardly the arm 33 to its inoperative position.

The arm or conveyer 46 is made in this instance of the shape shown inFigs. 2 and 3. The arm 46 has its hub 46', see Fig. 2, secured on thetransverse shaft 32. An extension 46, see Fig. 3, on the arm 46, engagesthe swinging lever 31. A helically .coiled expansion spring 47 acts toyieldmemos ingly hold the conveyer arm 46 in engagement with theswinging arm 31, to move therewith when the arm 31 is operated as abovedescribed. The lower end of the conveyer arm 46 has the enlarged portion46, see Fig. 4, which is adapted to enter the shuttle 47 between theholding jaws 48, see Fig. 6, for the head 11' of the bobbin 11.

Extending lips 46 on the end 46', are provided to hold the head 11 ofthe bobbin 11, which is released from the magazine. A spring blade 49 isadapted to reach under the head of the bobbin, see Fig. 4, which springyieldingly moves outwardly when a new bobbin is transferred into theshuttle, and the shuttle box moved downwardly.

The magazine end 10 is provided with an extension 10*, see Fig. 4, atits central portion, to force the head of the bobbin 11 into the shuttlewhen it is raised, as will be hereinafter described.-

The transverse shaft 32 has secured thereon, on its opposite end at theouter end frame 13 of the magazine, the hub 50', see Fig. 2, of adownwardly extending arm 50, which arm is adapted to carry at its lowerend 50", the tip of the released bobbin, see Figs. 1 and 2. Springblades 51 are provided, which yieldingly hold the tip of the bobbin 11in position.

We will now describe the mechanisms for raising the shuttle box whichcarries the shuttle, to receive a new bobbin from the conveyor, whichmechanisms are similar to those shown and described in Letters Patent,No. 935,645, above referred to.

The rock shaft 18 on the magazine carries in this instance a lever orarm 52, see Figs. 2 and 3. The end of the lever 52 has pivotallyconnected thereto the upper end of a downwardly extending connector rod53; the lower end of said connector rod 53 is pivotally connected to theend of a lever 54,,

see Fig. 2, which has its hub 54' fast on a short 55, which short shafthas a bearing 56 on a stand 56 secured to the 100m frame.

Also fast on the shaft is the hub 57' of the lever 57. The end of saidlever 57 carries a pin 58, to which is pivotally connected one end of ahorizontally extending connector. 59, see Fig. 1. The other end of theconnector 59 is connected to an extension 60 on a yoke shaped lever 60,which is pivotally mounted on a stud 61 on an arm 62. The yoke shapedlever 60 is adapted to move a starting tooth 63, in or out of mesh witha mutilated gear 64, fast on the bottom shaft 8, to cause the rotationof a mutilated pinion 65. The mutilated pinion 65 is loosely.

mounted on a stud 66, and is connected with an eccentric 67, to turnsaid eccentric. Also connected with the pinion 65 is a disk 68, having arecessed portion 68 on its periphery, into which is adapted to extendthe two rounded portions 69, in this instance on one tilt end of a lever69, see Fig. 1. The hub 69" of the lever 69 is pivotally mounted on astud 70 on the loom frame 1.

A helically coiled contraction spring 71 is attached at one end to thelever 69, and at its other end to a stud 71- on the frame 1, and acts toyieldingly hold the rounded portions 69' toward the disk 68, to causethem to enter the recessed portion 68 of said disk 68, to lock the disk67 in its inoperative position after it has made one full turn.

The eccentric 67 has an arm 67 thereon, which is pivotally connectedwith one arm of a lever 72, which has its hub 7 2 loosely mounted on astud 73 on the frame 1. The other arm 72" of the lever 7 2 is pivotallyconnectedwith a give-way device 74, which consists of two clamp arms,which are yieldingly held in engagement, by a contraction spring 75,with a stud 76 on the arm 72 of the lever 72. The clamp arms 74 arepivotally mounted at their lower ends on a stud 77, secured to the lowerend of the box lifter rod 78. The box lifter rod 78 has a bearing in astand 79 see Fig. 1, connected with the pivoted shaft or rod 5 of thelay sword 4, in the usual way. The upper end of the box lifter rod 78carries a yoke shaped frame 80, which carries at its upper end a shuttlebox or cell 81, to contain the active shuttle 47. The shuttle box 81 hasa vertical movement, and is vprovided with projections which extend intoguide-ways in the ends of the shuttle box guide frame 82, see Fig. 2.

By the raising of the shuttle box 81, the conveyor arms 46 and 50 enterthe shuttle 47, and a new bobbin is inserted from the eonveyer arms, andthe spent bobbin 11 will pass through anopening in the shuttle in theusual way.

The mechanism for detecting the practical or substantial exhaustion offilling in the active shuttle, is not shown. in the drawings ordescribed herein, but may be of any usual construction, and, connectedwith the weft by Letters Patent is 2- 1.
